I applied through a recruiter. The process took 3 weeks. I interviewed at Criteo
Interview
I had two Skype interviews. For the first they were 20 minutes late however it still went really well. For the second interview they went over by about 15 minutes so took 1hr 15m instead of just an hour. The interviewers were nice except in one of the interviews one of the people didn't speak at all and just stared at the screen.
The questions were coding exercises on a shared screen. They are nice people. I didn't get an offer and they took quite a long time to tell me that, and probably only because I emailed them to ask.
